Three major questions and answers of the Van Raam 3D Scanner

Van Raam is a manufacturer of adapted bicycles for people with a disability. The bicycles are manufactured in Varsseveld in one of the cleanest and smartest factories in the Netherlands. In our modern company, we have an innovative company policy and use innovative and modern techniques. To continuously improve these bicycles and remain innovative, Van Raam now also has a 3D scanner. Do you ask yourself what a 3D scanner is, why and what it is used for at Van Raam? Then read on and learn more!   


1. What is a 3D Scanner?

A 3D scanner is an innovative device that takes a 3D-image of an object. The result is a digital 3D model that is transferred to the computer.
The 3D Scanner Scanbox is a fenced room with a large turntable in the middle. Next to the table is a robot arm with a scanner. This scanner scans different objects on the disc using programmed movements and can thus digitally and fully autonomously capture these objects. This offers the possibility to control and adjust the production. It is also possible to then print them in 3D. Interesting to know: You can scan everything with the scanner as long as it is not moving and not too shiny or transparent. In the following, you can see some impressions of the Van Raam 3D scanner.

"In this way, the production process can be optimized and the quality of the customized bikes can be guaranteed."

2. What is a 3D Scanner used for by Van Raam?

Van Raam manufactures adapted bicycles for disabled people and people that no longer can ride a two wheel bike. Quality and innovation are of great importance. With the new 3D scanner, bicycles and individual bicycle parts can be scanned to create a digital copy of the 'real' bicycle. Then the 3D models and designs that were made before the R&D department manufactured the bicycle can be compared. Here, possible deviations can be identified. This are the four main resaons for Van Raam to use a 3D scanner.

  • Optimizing the production process
  • Guarantee quality
  • Further development
  • Staying innovative

3D Scan Van Raam Opair

You can scan an OPair wheelchairbike rear frame. On the basis of this scan, Van Raam has adjusted the welding mould for the welding so that the frame comes out of the welding robot is even better and more accurate and optimized. By the way, a scan can never have everything 100% green, which is almost impossible because tubes always warp due to the heat during welding.

In this way, the production process can be optimised and the quality of the adapted bicycles can be guaranteed. Since the laser robots and the welding robots can then be quickly adapted if necessary. Based on the outcome of the scan data. Do you ask yourself how often this happens? During production, random scans and other tests are carried out regularly.
 

"A scan of the frame from the Fun2Go side by side tandem takes 5 minutes."

3. How does a 3D Scanner work?

The GOM brand ATOS Scanbox uses lasers to provide a full-field 3D coordinates for each measurement. Within a few seconds, up to 16 million independent measuring points are captured per scan. The turntable in the scan box automates the entire process. Thus, the object does not have to be turned manually in all directions.

The scanner projects a grid while the camera measures the formation of the object. The angle between the camera and the laser, the distance between the camera, the laser and the object are used to determine the spatial coordinates of the object. Reference points on the rotating plate allow the scanner to determine the dimensions of the object and to easily fit multiple scans together to create one 3D-model. A positive advantage is that it has a high accuracy level of 0.02 mm. As a result, the measuring data is characterized by very high detailed reproduction, thereby enabling very small component features to be measured.
